Install wok, gingerbase, ginger and gingers390x plugins on s390x architecture.

1. Navigate to "Host" -> "Network" -> "Network Configuration" section. click on "Add" -> "Add Adapter".
   select any device from "Offline Devices" list,,click on "Enable"
   pop-up appears for "OSA Port" selection.

the "note" in the pop-up doesn't get required attention from user since looks kind of hidden between "i" symbol and '*'.

2. Navigate to "Host" -> "Network" -> "Network Configuration" section. click on "Add" -> "Add Adapter".
   select any device from "Offline Devices" list,,click on "Enable", select osa port and click on "Apply".

The "loading" message cannot be seen properly, and offline devices list should be completely faded highlighting 'loading' message ,,also "Finish" button should be disabled.
